1907FP monitor won't slide back up stand

So I set up my new up and while doing so slide the actual display down the stand. During this time, I wasn't pressing any button on the stand.

The display locked into place at the bottom of the stand, and I can't figure out how to move it back up. The button on the back of the stand does nothing, as far as I can tell. When I press it, the button barely even moves.

You are amazing! This totally worked! When I read what you wrote, I associated the answer with what I have to do in my car when my steering wheel gets locked. I have to shimmy the wheel while I turn on the car, or else the ignition won't start.

Don't be sorry about this post!! If it wasn't for you asking this question, I would still be surfing the net for an answer on how to fix mine! I work in a building full of engineers and there are several of them that locked in place...they just set the monitors to the side and started using other ones! hahaha
